Abstract

This paper presents a soft-switched ac-dc symmetrical boost converter with power factor correction. The rectifier is modified boost voltage that is well suited for low line input applications and operated with half of the switch voltage stress than those found in standard boost converter. Soft-switching in the boost converter is achieved under zero-voltage switching (ZVS) turn on and zero-current switching (ZCS) at turn on, quasi resonant technique. In this paper, the operation principle and operation mode are demonstrated. The experimental results obtained from a prototype are agreement with the simulation ones.
